Specification of Letters Patent.

Patented July 9, 1907.

Application filed November 22,1906. Serial No- 344,570.

To all whom it may concern:

Be it known that I, GEORGE M. Corn, a resident of Pittsburg, in thecounty of Allegheny and State of I Pennsylvania, have invented a new anduseful Improvement in-Raih'o-ad-Ties; and I do hereby declare thefollowing to be a full, clear, and exact description thereof.

My invention relates to railroad ties and has spemetallic tids for usein supporting rails thereon. 4'.-

The object of my invention {isrto provide a cheap, simple and efficientform of a railroad tie which can be easily and cheaply' manufactured,will firmly hold the rails thereon and will allow the attaching of therails thereto, while at the same time such a tie as will permitexpansion and contraction therein and sufiicient resiliencyf or thepurpose intended.

My invention consists, generally stated, in the novel construction of atie, as hereinafter more specifically set forth and" described andparticularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains toconstruct and use my improved tie, I will describe the same more fully,referring to the accompanying drawing, in which- Figure 1 is a plan viewof a plate ready to be formed into my improved ltie; Fig. 2 is aperspective viewof the tie in shape ready for use. Fig. 3 is an enlargedend view of the tie. Fig. 4 is a perspective view of a portion of thetie showing a portion of the rail thereon and attached thereto.

Like symbols of referende herein indicate like parts in each of thefigures of the drawing.

As illustrated in the drawing, 1 represents the tie which is preferablyformed from a plate or a sheet of metal a and cut to the proper size andshape'and bent to a four sided form in cross-section by rolling In suchbending of the plate or sheet a the metal thereof is bent or foldedaround in order to provide for the hollow tie 1 having the chamber 2through-the same, the fiat top 3 and the inclined or outwardly flaredsides 4 leading from said top, and such sides connect with the portions5 for the flat bottom 5 of the said tie. When the metal of the plate orsheet a is thus brought to shape toform the said tie 1, the side edges 6of said sheet in forming the bottom 5 will come opposite each other andform the longitudinal slit, space or opening 6 between them.

In my application filed on September 17, 1906, shown a construction of arail support for use with ahollow tie substantially like the tie 1,which consists, generally, of az-shaped clamping-bar '7 engaging at oneend withthe base of the rail A on the top 3 and passing thi'ough an opening or hole 8 ii: said top 3 of the tie 1, so that the opwhile a plate10 fits around ing the portions 5 posite end of said bar located withinthe said tie can bev engaged by a bolt 9 passing through said top, saidbolt. on the top 3 and is provided with a spring lip 11' thereon forengaging with the head of said bolt to lock the same in place. In theuse of such a rail support the holes 8 for these rail supporting bars'7and the holes 9 for the bolts canbe formed in the plate abefore it isformed into the tie, as shown in Fig. 1, andby reference to said plate,as shown in said figure, the dotted lines indicate the points of bendingin forming the tie 1 and the part between the dotted lines. 0" indicatesthe portion for forming the top 3, the part between the lines 0 and'dindicates the portion for forming the inclined sides 4, while the partbetween the lines d and the side edges b of sai plate indicates theparts for formcomposing the fiat bottom 5.

It will be obvious that my improved tie may be of material other thanmetal and that various modifications and changesin the design andconstruction of the same may be resdrted to without departing from thespirit of the invention or sacrificing any of its advantages. It willthus be seen that my improved railroad tie will provide for a springyaction within the same in the passing of trains same, by reason of theformation of its sides and they can be made in a rapid and convenientmanner through rolling in specially formed dies, and also by a pressingoperation, sothat the tie is complete and ready for instant use. It willbe lasting over the and durable and will not be liable to spread, breakor get out of shape.

What I claim as my invention and desire to secure by Letters Patentis 1. A tie for rails formed from a plate or sheet into a hollowfour-sided shape in cross-section and having openings in the top of thesame, its sides outwardly flaring from the top of. the tie and toprovide for an opening or 2. A tie for rails formed from a plate orsheet into a hollow four-sided shape in cross-section by bending andhaving openings in the top of the some. its sides outwardly flaring fromthe top of the tie and its bottom slit longitudinully to provide for anopening or space therein.

22. A tie for rails formed into a hollow four sided shape incross-section and having openings in the top of the same. its sidesoutwardly flaring from the top of the tin and its bottom slit.longitudinally to provide for an opening or space therein.

4. A tie for rails formed from n. iuetalllc plate or sheet into a hollowfour sided shape in cross-section by bending and liaving openings in thetop of the sin-me, its sides outwardly fiaringfrom the top of the tieand its bottom slit longitudinally to provide for an opcningor spacetherein.

In testimony whereof, I the said Georges M. Corn have hereunto set myhand.
